You would do very well to steer clear of the deadbolts sold under the "Constructor" brand at Walmart.com. Most likely these inferior products are not sold at the actual brick and morter Wal-Mart locations. There are documented customer complaints that the product they receive in the shipping carton is scuffed as if someone already used the lock. What is probably happening is that once the item is removed from the box and the customer realizes that the lock cant be rekeyed, it goes back in the container to be shipped back for a refund. These locks are truly second-rate in every sense of the phrase .  Watch this video https://www.youtube.com/watch?v=UHaYxeHZLdg  to see my comments and some closeup views of the components.  Do yourself a favor and throw these away if you purchase a home with them. They are unsecure and of extremely low quality. Poorly designed and manufactured hardware will most certainly cost you in the future. You will be fortunate if it is only a financial loss that you experience.
